Figure 1. Sequence alignment of barnacle pigment dispersing hormone, SIFamide and neuropeptide F with arthropods.

Figure 1

(A) Sequence alignment of mature pigment dispersing hormone. Decapods peptide sequences are from: Uca pugilator P08871, Procambarus clarkii Q9TWW7 and Cancer productus ABV68725; isopod peptide is from Eurydice pulchra ACX49752; insect peptides are from: Drosophila melanogaster AAL49303, Schistocerca gregaria ACY02888 and Musca domestica Q76JT9. (B) Alignment of barnacle SIFamide mature peptides. Sequences are from: decapods Homarus americanus, Cancer borealis; branchiopod Daphnia pulex; insects Drosophila melanogaster, Tribolium castaneum, Bombyx mori, Rhodnius prolixus and Ixodes scapularis [38]. (C) Alignment of barnacle NPF mature peptide. Insect NPF are from: Drosophila melanogaster AF117896, Bombyx mori NP_001124361, Locusta migratoria CO854418 and Pediculus humanus EEB15547. Decapods NPF are from shrimps Marsupenaeus japonicus CI998017 and Litopenaeus vannamei AEC12204; copepod NPF is from Lepeophtheirus salmonis FK933794; branchiopods NPF are from Daphnia magna EG565358 and Daphnia pulex EFX90018. Asterisks “*” represent typical motif residues of each peptide. “x” indicates unique amino acid residues of B. amphitrite compared to other arthropods. Line marks the unique five amino acids insertion of NPF in B. amphitrite.
